Here is a note, if your method take the exchange as the parameter, the return type must be void.
Spring configuration example <camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring";> <from url="COSUME_XML_URL"/> <to url="bean:bar?method=doSomething"/> <to url="mail:xxx"/> </camelContext> <bean id="bar" class="xxx.Bar" /> Java example, you need bind "bar" with the Bar's new instance in the JndiContext, or you create a SpringCamelContext to load <bean id="bar" class="xxx.Bar" />, then add the route rule with below code. from("COSUME_XML_URL") .to("bean:bar?method=doSomething") .to("mail:xxx"); You can find more bean unit tests here[1] [1] https://svn.apache.org/repos/asf/activemq/camel/trunk/camel-core/src/test/java/org/apache/camel/component/bean Willem Franklin Antony wrote: > But if I had a method as follows > > public class Bar { > > public String doSomething(Exchange exchange) { > // process the exchange > String newFileName=SprringService.generateFileName(); > > exchange.getIn().setBody("Bye World"); > > return newFileName; > > } > } > > Would this be possible? > > If so how would the route be written in Java and XML ?? > > Thanks, > Franklin. > > > > > > willem.jiang wrote: >> Hi Frank >> >> Basically if you want to set the result object back into message body, >> you just need to return that result object in your method, camel-bean >> will take care of it. >> >> BTW, you can also pass the Exchange into your bean's method like this >> so you can set the result object yourself. >> public class Bar { >> >> public void doSomething(Exchange exchange) { >> // process the exchange >> exchange.getIn().setBody("Bye World"); >> } >> } >> >> You can find more information about how to use bean in camel here [1][2] >> [1] http://activemq.apache.org/camel/bean.html >> [2] http://activemq.apache.org/camel/bean-binding.html >> >> Willem >> >> Franklin Antony wrote: >>> Thanks Willem.
